Final answer:
Christopher Columbus argued that Europeans could reach the Indies by sailing west and received financial backing from Spain for his voyage.
Step-by-step explanation:
In the latter half of the fifteenth century, Christopher Columbus argued that Europeans could reach the Indies by sailing west, rather than east. He believed in the existence of a shorter route to the riches of Asia. Columbus received financial backing from Queen Isabella and King Ferdinand of Spain for his westward voyage. Although he did not find a direct route to the Indies, his expeditions led to the exploration and colonization of the Americas.
